Seeking advice for Cyclone build

[loysius]

Hi guys,

Please let me know your opinions on this mid motor build. I'm shooting for durability and performance so let me know if there are better options.


------------------------------------------------------


Bike: Hardtail Raleigh, using one of our used bikes. BB is JIS 68-73mm haven't measured the width yet.

Motor&Controller kit: (upgraded mount)Cyclone 3000w mid,
https://laebike.com/collections/diy-mid-drive-kits/products/edge-3000w-mid-drive-kit

Monitor: CAv3

Battery: 72v 50-70amp bms,
http://lunacycle.com/hot-new/72v-panasonic-pf-11-6ah-with-luna-charger/

Chain: 1/8" bmx,

Rear Cassette spacer:

Rear Single-speed, 17t(steel):

Front Chainring: 44-32-24t, 3 speed chainring from a Specialized



------------------------------------------------------


So the bike currently has a 9sp cassette so I'm not sure if this spacer is right. Potentially the different spacers in the kit will let me line up an optimal chain-line. I picked out the 17t rear sprocket because I figure it would be speedy yet still substantially stronger than a 11t. Is that strong enough? I don't know. I'm thinking front derailleur would be a good way to go since just 3 gears would be great and I already have the parts left over from another bike's conversion to a BBSHD.

Are there any other ideas or options I should consider? Maybe a belt drive by Gates would be better?


Thanks,
Al

Have you seen this Cyclone thread?

I would just use the stock cassette to start. Would it be much different from leaving it in a single gear and not shifting the rear? You'll have 3 chainrings up front, but you can only use 2 of them since the Cyclone will be driving one. If you're after longevity, you should use the gears in the back. This way you can reduce the tension on the chain (reducing the wear on everything), and you'll gain efficiency (by allowing the motor to spin faster).
